maksolino Posted June 29, 2010 Share Posted June 29, 2010 hello again i need a script to Slide a point along a curve The command DIVIDE whith option Lenght , start always from the beginning of curve. I found this RhinoScript but it works only whith Rhino 4 . Rhino 3 don't support the command CurveArcLengthPoint. Can somebody make a similar script for Rhino 3. Thanks ' Option Explicit Sub OffsetPointOnCurve ' Select the curve Dim crv : crv = Rhino.GetObject("Select curve", 4) If IsNull(crv) Then Exit Sub ' Select a point on the curve to offset from Dim pt : pt = Rhino.GetPointOnCurve(crv, "Select point on curve") If IsNull( pt) Then Exit Sub ' Specify the offset distance Dim dist : dist = Rhino.GetReal("Distance to offset point") If IsNull(dist) Then Exit Sub ' Get the closest point on the curve from the test point Dim t : t = Rhino.CurveClosestPoint(crv, pt) ' Get the curve's domain Dim d : Dom = Rhino.CurveDomain(crv) ' Get the total length of the curve Dim l : l = Rhino.CurveLength(crv) ' Determine the length from the start of the curve to the test point Dim ls : ls = Rhino.CurveLength(crv,,Array(Dom(0),t)) ' Offset a point in each direction Rhino.AddPoint Rhino.CurveArcLengthPoint(crv, ls + dist, True) 'Rhino.AddPoint Rhino.CurveArcLengthPoint(crv, l - ls + dist, False) ' Add the test point for reference 'Rhino.AddPoint pt End Sub Quote Link to comment Share on other sites More sharing options...
